Claims. (Cl. 242-355) The present invention relates to the winding oftextile yarns'and particularly to a mechanism utilizing a rotary yarnguide and producing various types of winds such for example as ligureeights, spiral or straight, the change from one type to another beingreadily effected.

The invention is shown in connection with a machine which takes yarnfrom a supply package, sizes the yarn andV winds it on a tube, althoughyarn may be wound in this manner and the sizing step omitted.

It is an object of the invention to provide a yarn winding machine inwhich various types of winds can be produced.

t is another object of the invention to produce these various types ofwinds by means of a rotary yarn guide the rate of rotation of which canbe varied as respects the rate of rotation of the tube on which the yarnis wound.

It is a further object of the invention to provide such` sizing andwinding machine having incorporated therein the rotary yarn guides of myinvention;

Figure 2 is a fragmentary side elevation of the machine lof Figure 1';

Figure 3 is an enlargedside elevation of certain of.

the rotaryl yarn guides; and

Figure 4 is an enlarged cross-sectional view'of one of the rotary yarnguides showingalso the positioning of the driving and supporting belttherefor and ofthe guides for that belt. The section is taken on theplane of the line 4-4 of Figure 3.

Referring now to the drawings and particularly to Figure 1 there isshown at 10 a suitable frame for supporting the yarn winding apparatus.Vertically reciprocable upon the frame 10 are the rods 12 on which aremounted the traverse bars 13 which bars support the rotary guidemechanism in the manner to be described. Rods 12 are guided in bearings14 and are caused to reciprocate under motor drive in any suitablemanner such for example as the cam drive disclosed in my Patent No.2,635,820, issued April 2l, 1953.

Extending longitudinally of the machine are pipes or tubes 16 mountedupon the intermediate frame members 17 iixed to the frame 10. Mounted onthe pipes 16 are the supporting members 18 on which spindles 26 arerotatably mounted, these spindles being driven by a belt 21, the beltbeing guided and held in place against the spindles by means of theidler rollers 22.

Mounted on the traverse bar 13 at spaced points therealong are brackets23. Supported on the brackets 23,

ECC

as shown particularly in Figure l, are longitudinally extending plates24, these plates having circular openings therein, the vertical centerline or these openings being slightly displaced from a side edge of awinding'tube 26 mounted on an extension 25 of the spindle 20. As seen inFigure 2 the vertical center line of the circular opening is displacedslightly to the left of the left edge of each winding tube 26.

Extending forwardly from and iixed to each plate 24 adjacent the lefthand edge of the circular opening mentioned, is a strip of librematerial 27 which cooperates with another like strip to form a brake.Mounted at either end of the plates 24 (one on either side of themachine) are pulleys, one of which is indicated at 28 1n Figure 2.Adjustably mounted, as for example by means of the eccentric screws 29shown in Figure 3 at spaced points adjacent the upper and lower edgesofeach plate i 24, are ball bearing idler rollers 36, together with beltguides-31. A belt 32 passes over the pulleys 28 and bears against theidler rollers 3l).

As will be observed by reference to Figures l, 3 and 4, the idlerrollers 3Q are arranged in groups of four, two of which cooperate withthe lower reach. of the belt and two with substantially correspondingpoints on the upper reach of the belt. A rotary yarn guide 33, which isshown as a ring having a ilanged rim is arranged at substantially thecenter of the rectangular figure formed by a group of idlers 3i), theyarn guide 33 being supported upon the Vlower reach of the belt and heldin place by reason of the belt passing between the flanges thereof.Further, since one pair of diagonally opposite rollers 3l) (the pair atthe upper right and lower left m FiguresZ and 3) is adjusted to becloser to the horizontal center line ot' ring 33 than the other pair,the rings arelocated laterally' asV Well as vertically by belt 32.

As has already been stated, a vertically extending bre piece 27 ismounted on the plate 24 adjacent-.the left hand side of each of thecircular openings in the plate 24. This fibre piece extendsbetweentheupper and lower reach of the belt and forms a part of a brakemechanism.

Each rotary yarn guide is provided with a V,srnalleye xed to the innersurface thereof as indicated lat 34 and the yarn extends through thiseye.

`Lying on theopposite side of each yarn guide 33 from thefbre brakepiece 27 already described is a similar nbre piece 35, this piecehoweveibeing supported on an arm 36 oscillatably mounted .on av stud xedto the plate 24. Integral with the arm 35 is an operating lever 37guided in a guide member 38 fixed to the plate 24 the lever being heldinveither of Yits adjusted positions by means of the screw 4i? operatingin a central slot in the member 41. Thus by raising lever 37 to itsupper position the rotation of the associated yarn guide 33 may bestopped by gripping the guide 3i) between the two fibre brake pieces 27and 35.

When the brake levers 37 are in their lower position the yarn guides arefree to rotate being driven by belt 32 which is in turn driven by thepulley 28. Pulley 28 has mounted on its shaft a second pulley 42. AV-belt 43 extends from a pulley 44 to the pulley 42. Pulley 44 isrotatably mounted on a shaft 45 supported on an arm 46 pivotally mountedon the frame 10. A link 47 extends from the end of arm 46 to thetraverse bar 13, this link serving to maintain the relationship betweenpulleys 42 and 44 and thus keep the belt 43 taut irrespective of thevertical position of the traverse bar 13.

Mounted on the shaft 45 is a second pulley 48 driven` by a pulley 50mounted on shaft 51, shaft 51 also constituting the pivot point for arm46. A V-belt 52 extends from pulley 50 to pulley 48. Shaft 51 is drivenby means of a pulley 53 xed thereon, a V-belt 54 extend- A yarnsupplypackage is mounted in any suitable y position on the machine frame asindicated, for exarnple at 55. The yarn from this package passes througha guide V56, thence upwardly through a tensioning device 57, through ayarn cleaning member S, and thence over the outer surface of a sizingroll 60, which roll is mounted on a shaft 61 driven in any suitablemanner from the machine motor and operates in a trough 62 containingsizing material.

From the sizing roll the yarn passes over a yarn guide '64 fixed to arm65 which is in turn xed to the plate 24, thence through the eye 34 ofthe associated rotary yarn guide 33 and to the tube 26. As the tubes 26rotate at high speed the rotary guides also rotate thus producing aconical path between each rotary guide and its associated tube or bobbin26. As this occurs the traverse 13 moves slowly up and down. As a'resultand depending upon the speed ratio between the rotary guides 33 and thespindles 20, 25, various types of winds such as figure eights,spiral'ror straight can be effected and deposited layer upon layer untilthe tube is full. Moreover, the movement of the rotary guides 33produces a taper at each end of the tube giving a crowned or barreleffect. The various types of wind which may be produced determinewhether the package is to be hard or soft; package hardness may befurther controlled by varying the tension applied in the tensioningdevice 57.

While I have described a preferred embodiment of my invention it will beunderstood that many other modications may be made without deviatingfrom the principles thereof; therefore I wish to be limited not by theforegoing description, but solely by the claims granted to me.
